基于移动Sink的多拷贝路由冗余消除方法

Redundancy removing method for multiple-copy routing based on mobile Sink

采用Epidemic routing多拷贝消息路由方法,提出了一种基于移动Sink节点相遇次数阈值的消息拷贝冗余消除机制,不但保证了消息成功传递,而且有效地减少了网络中的消息拷贝数,降低了因大量拷贝引起的缓存、带宽和能量等资源的消耗。理论分析和仿真实验表明,选取合适的阈值可使传递成功率保持不变,而且传递延迟和到达AP的跳数不会增加。

Using multiple copies method of epidemic routing we propose a redundancy removing method for message copies based on the threshold of encounter number of mobile Sink nodes each other. The method not only guarantees the successful transfer of message but also effectively decreases copies in the network to reduce the consumption of resource, buffer, bandwidth and energy caused by large amount of copies. Theoretical analysis and simulation experiment show that the delivery efficiency stays the same, the delay and hop count do not increase with the appropriate threshold.
